To all whom it may concern:

Be it known that l, Fmnnnmor-r WILLIAM Bones, a citizen of the United States, residing in the town of Rosedale, in the county of Baltimore and State of Maryland (whose post-otlice address is Philadelphia Road and Hamilton Ave, Raspeburg lt. D.), have invented a new and useful Improvement in a Motor Fuel.

l his invention rel-ates to liquid fuel for use in internal combustion engines, and has for its object toprovide a fuel, which, due to possessing greater, specific gravity than the common, commercial form of gasoline, is

heavier and gives a slower combustion, which will permit ofa'higher spark advance to the engine than heretofore possible with the' ordinary type of fuel now onthe market.

By reasonot the utilizing of a heavy fuel comprising the ingredients in the proportions herein set forth, it is obvious that a considerable saving will be effected in the consumption of the fuel, as the same will not be drawn off and burned as Wast/efully from the jet of the carburetor as the lighter and more volatile fuels.

The principal power-giving element of the uel is gasoline, which is admixed with acetone, kerosene, and benzol, in substantially the proportions below set forth.

A motor fuel compounded in accordance with my invention will greatly-increase the mileage per gallon of the fuel, and at the same time improve the eiliciency and increase the durability of the motor, as it will not corrode or have any other detrimental effect upon the'engine parts.

Furthermore, the fuel has the effect of keeping the carbon in the cylinders in suspension, preventing its hardening on to the metal surfaces, and thus permitting the said free carbon to be expelled through the exhaust.

To obtain a liquid fuel that will giv the desired results, has been -lound, from practical experimentation, that at a per-attire 0510 E, following in 'redients compounded in the following proporions are highly satisfactory.

Acetone 3 Kerosene 3 liq. oz. or approximately 3% Specification of Letters Patent.

Patented 8, 15922.,

Application filed February 28, real. Serial No. 1423248.

While kerosene and gasoline are by-products of petroleum distillate, the total percentage of these two ingredients, called for in the above formula, may be taken together and considered as the amount or petroleum distillate employed.

To compensate for changes in atmospheric temperatures, it has been found advantageous to vary the proportion of benzol, vary"- ing from approximately 7% to 27%, without any variation being made in any oi the other ingredients. I

The yarying of the quantity of benzol used has been found desirable, since benzol at a very low temperature has a tendency to change from the fluid to the solid state, and this 'congealing naturally tends to impair the efilciency of the fuel, it not proportionately lessened as the temperature decreases. Conversely, the benzol must be proportionately increased as the temperature rises. thus varying the quantity of the benzol as the temperature changes, a heavy and slowly burning fuel is obtained which will permit of a higher spark advance, and a reduction in the consumption of the "fuel.

The acetone, due to its mobility, tends to produce better vaporization of the fuel, thus causing the engine to start much easier. lt also counteracts the heating effect of the henzol and assists materially in keeping the temperature of the engine at a proper point- The kerosene tends greatly to facilitate the mixing and blending of the acetone with the gasoline, and also prevents the too rapid vaporization of the acetone.

Another irnportant advantage residing in the use oikerosene is, that it acts, in combination with the acetone, as a solvent of the carbon developed in the cylinders, and causes the carbon'to remain continuously in suspension so that the vtree carbon is readily expelled with the exhaust gases, so that carbon deposits in the cylinders are eliminated or minimized.

my invention, l am able to materially cut down the use of gasoline, and yet secure a fuel which ishigh in power and in mile= age per fuel unit, and which will have a lower vaporization point n commercial gasoline, so losses from excessive rapid vaporization are materially reduced.
